Socket bit 6-point 1/4" 8 mm Hartsson 17A108Z

Hartsson 6-point socket bit with a 1/4" drive and 8 mm hex size is a compact tool insert engineered for fastening and loosening hexagonal fasteners. The 6-point profile engages flat sides of fasteners for improved torque transfer, and the 1/4" drive format makes the bit compatible with standard 1/4" bit holders, screwdrivers and ratchets. Constructed from metal for routine workshop, automotive and home maintenance tasks, this 8 mm socket bit is intended as a reliable replacement or addition to small tool kits where a standard 8 mm hex socket is required.

Advantages

The Hartsson 6-point 8 mm socket bit provides a precise fit to standard hex fasteners and reduces rounding compared with multi-point profiles. Its 1/4" drive size ensures broad compatibility with common bit holders and hand tools, while the compact metal construction offers durability for repeated use in workshop and automotive environments. The simple design enables quick insertion and removal from drivers and extensions, supporting efficient workflow on assembly, repair or maintenance tasks.

Suitable for

• General workshop fastening and loosening of 8 mm hex bolts and screws
• Automotive repairs where a compact 1/4" drive socket is needed
• DIY and household maintenance tasks requiring an 8 mm hex socket
• Use with 1/4" bit holders, screwdrivers, ratchets and extensions

Key specifications

• Drive size: 1/4" compatible
• Socket profile: 6-point (hexagon)
• Nominal socket size: 8 mm
• Construction: metal socket bit designed for manual and light power tool use
• Form factor: compact bit for bit holders and short extensions

How to use

Insert the 1/4" drive end of the socket bit into a compatible bit holder, screwdriver or ratchet. Place the 6-point 8 mm end squarely over the head of the hex fastener to ensure full engagement with the flats. Apply steady torque while turning to tighten or loosen the fastener, avoiding side loading that can cause wear or rounding. After use, store the bit in a bit set or holder to protect the working end and maintain fit accuracy.

Usage recommendations

Use the socket bit with hand tools or low-speed drivers to maintain control and prevent damage. Match the 8 mm size precisely to the fastener and avoid applying excessive torque beyond the fastener or tool rating.
